Answer: I don't have rupee sign so I ll use dollar $ instead of ruppee
total cost of flooring = 2048$
cost of flooring per m²= 64$
the area of the rectangle= 2048$/64$/m²
= 32/1/m² (cut both the dollars/rupee)
= 32m²
now area of rectangular floor= l*b
=> 32m²= l*5m
l= 32m²/5m= 6.4 m
perimeter of the rectangle = 2(l+b)
= 2(6.4+5) m
= 2(11.4) m
=22.8m
hope this help
